On: WebAssembly on the Server: How System Calls Work

I assume that new chips will address this vulnerability, correct? Couldn't the VM detect whether the hardware is secure and decide whether to use hardware memory protection or not?

At this point it seems practically impossible to deal with completely.

V8 at least have given up on the concept of trying to protect memory within the same address space.

It doesn't seem likely. The chipmakers will fix the vulnerabilities that break isolation between processes and between user-kernel, but the within-process issues will probably stick around.
